APAR status

  • Closed as program error.

Error description

  • Page reload looping can be observed if a PZN rule makes a
    Portlet invisible and the LayoutModel feed was requested before
    that. In this case the LayoutModel feed is cached by the browser
    and the Web 2 theme requests the Portlet-Fragment but the
    Portlet is already invisible in the current model. This leads
    the Portlet-Fragment request to return the whole page markup.
    
    This fix changes the behaviour to return a HTTP 404 Not Found
    error in case an invalid Portlet-Fragment was requested.
